How upheavals in accepted scientific theories helped popularize the term 'paradigm'

Science is rarely a linear progression of understanding

Particularly at the frontiers, investigations conducted based on established knowledge can provide unexpected results. This opens the door to revising existing models, inspiring new lines of research, and ultimately leading to better future comprehension. For instance, experiments on the speed of light and the expansion of the universe yielded then-confusing data that led to revolutionary insights.

Enlightenment ideals of reason informed the foundation of the Revolution

From the 17th to 19th centuries, an intellectual movement took place in Europe and its colonies that emphasized reason over authority. Following the Scientific Revolution, thinkers like Descartes, Kant, and Locke sought to explain the world in rational—rather than religious—terms. The movement caused a paradigm shift in how societies are organized and how people perceive themselves.

How 'Star Wars' changed science fiction

The popularity of "Star Wars" shifted the market away from the more literary, and sometimes cynical, science fiction of the 1960s and '70s. In the wake of George Lucas' space opera, publishers and studios wanted similarly optimistic adventure stories. In time, though, writers like William Gibson would react against that and, in turn, create the "cyber punk" subgenre.

Before Dawkins, other biologists proposed the power of mutating ideas

Nobel Prize winner Jacques Monod proposed, “Ideas have retained some of the properties of organisms. Like them, they tend to perpetuate their structure and to breed; they too can fuse, recombine, segregate their content; indeed they too can evolve, and in this evolution selection must surely play an important role.”

Pulitzer Prize-winning historian Edward Larson explores the Scopes Monkey Trial

The 1925 Scopes Monkey Trial was referred to as the "Trial of the Century" at the time, and has been since viewed as one of the origins of modern culture wars. A symbolic clash between science and religion during a period of rapid cultural change, the case became a flashpoint of differing ideologies.

An interview with James Yorke, the man who coined the mathematical term 'chaos'

Along with co-author Tien-Yien Li, the former University of Maryland mathematics department chair published the paper, "Period Three Implies Chaos" in 1975. "Chaos" then became the terminological placeholder for systems with sensitive dependence on initial conditions, which had been well known to mathematicians for over a decade.

Tracing the history of the philosophy of human extinction

Global catastrophe is at the center of much contemporary debate over climate, war, science, technology, and more, and our period is marked by a lurking sense everything we know—including the human species—could end overnight. It wasn't always...

Retracing the 1960s history of dropping out

A core element of the 1960s counterculture was the idea of dropping out of school and the broader technocratic institutions at the time. This push coincided with paranoia over mind control during the Cold War, and as some rogue psychologists advocated for the liberating use of psychedelics.

According to Bill Nye, science is under threat from an erosion in critical thinking

He states that conducting research online cannot replace consulting with scientific experts who have spent their entire lives intimately studying a field. The former science education show host argues that deepening cynicism towards scientific institutions has been fueled by leaders embracing debunked and unsupported claims.

The 'overview effect' heightens one's sense of unity and connectedness

Coined by space philosopher Frank White in 1987, the term refers to the paradigm-shifting experience a person undergoes upon viewing Earth from space. Commercial spaceflights aim to bring this perspective to a broader audience, inspiring changes in behavior and worldview among participants.

'It's those who lie outside ordinary experience who have the most to teach us.'

- Author Malcolm Gladwell (1963 - present)

After the USSR's fall, many experts believed liberal democracy had permanently prevailed

Political scientist Francis Fukuyama argued in 1992 that liberal democracy and market capitalism had defeated their ideological opponents and would eventually spread everywhere—a thesis he called "the end of history." Subsequent decades complicated that claim.

Despite his disability, Stephen Hawking reshaped our understanding of black holes

His theoretical work—especially on black holes emitting radiation, now known as Hawking radiation—challenged long-held ideas. He also brought complex physics to the public through bestselling books like "A Brief History of Time."

'Freakonomics' celebrated its 20th anniversary in 2025

The book 'Freakonomics' arguably changed the business landscape when it came out, and has since evolved into other forms of media and a cultural phenomenon.

A list of five scientific theories that were accepted and later disproved

Humoral theory held that everyone's personality derived from different combinations of four bodily fluids: blood, phlegm, yellow bile, and black bile. The phlogiston theory stated that all combustible materials possessed a fire element—phlogiston—that was released and absorbed by the air during burning. When the air became saturated with phlogiston, the fire would go out.

The Big Bang theory explains the expanding universe and its fiery early origins

The term “Big Bang” was initially coined by a skeptic of the theory, but the name stuck despite the theory not depicting a "bang." The event took place everywhere in the universe at once, and the theory explains the abundance of hydrogen and helium in the universe.

The theory of plate tectonics first emerged from the theory of continental drift

German meteorologist Alfred Wegener proposed that the continents were all one giant landmass in the past, which he named Pangaea. Despite geological and climate evidence suggesting continental movement, his theory was dismissed until the 1960s.

MoMA hosted 1962's 'Symposium on Pop Art,' which made the term 'pop art' official

MoMA's history with pop art and its conceptual roots extends to its early origins, and its collection of works includes iconic works like Warhol's "Campbell's Soup Cans" and Lichtenstein's "Drowning Girl."

Many writers considered 'existentialist' didn't identify with the term

“Existentialism” was first introduced in 1943 by philosopher Gabriel Marcel. Jean-Paul Sartre and Simone de Beauvoir readily adopted the term, but others, such as Albert Camus and Martin Heidegger, rejected it. Earlier philosophers, like Søren Kierkegaard and Friedrich Nietzsche, were long dead by the time the word was in vogue.

Philosophers have debated the nature of time since at least the 6th century B.C.E.

Greek philosopher Parmenides of Elea was skeptical of time and reasoned that if it were real, then the present would emerge from nothing because the future did not yet exist. Just as the color red is our perception of a specific wavelength of light, others have suggested time is a psychological projection based on how we interpret the world.

Later in life, the clock in Grace Hopper's office ran counterclockwise

Acknowledging that most people have "an enormous tendency to resist change," Hopper's clock served as a reminder for the computer scientist that just because things have been done a certain way does not mean they should forever remain that way: "They love to say, 'We've always done it this way.' I try to fight that." (Some users may experience a paywall.)

Whitman revolutionized American poetry

Whitman was a groundbreaking force in American literature, legitimizing the national idiom, capturing the spirit of the evolving country, and inspiring younger generations of writers for centuries to follow.

After surging in popularity, King began using a pseudonym

King was a rarity in the '70s: a genre writer with a vast mainstream audience. He was so popular, in fact, that he began releasing books under the pseudonym Richard Bachman, a ploy that allowed him to write outside the horror genre without attracting the displeasure of his massive fan base.
